At high temperatures monolithic materials can no longer fulfill all requirements posed by advanced energy conversion applications. It will be shown how diffusion couples can be used to study metal-ceramic interactions and to develop composite materials. Attention is paid to the development of a hot shell for a combustion heated thermionic energy converter operating at 1450°C. It will be shown how the combination of chemical and physical requirements leads to the design of a trilayer material, consisting of a W emitter, coated with a diffusion barrier of TiN and an outer protective shell of SiC.
